MANN: ANTS OF THE BRITISH SOLOMON ISLANDS. 391 



little convex, the suture indicated by a very shallow and indistinct impression; 

 subangulate between base and declivity. Epinotal spines nearly straight, a 

 little shorter than their distance apart at base. Petiolar node subtriangular 

 in profile, the dorsal edge margined and bearing four spines, the inner pair of 

 which are triangular, as broad basally as long, and the outer elongate-triangu- 

 lar, acute apically and four times as long as the inner pair. 



Moderately shining. Finely coriaceous and with minute punctation. 



Very fine and short recumbent pubescence thinly distributed on head, body, 

 and appendages. 



Color black. 



Malaita: Auki. 



Described from a unique worker. 



This species is near leonidas Forel, but is distinctly smaller, the meso- 

 epinotum is much less convex, the spines smaller and more cylindrical 

 and the outer pair of petiolar spines very much longer in proportion 

 to the inner pair than in a cotype of leonidas in Professor Wheeler's 

 collection.
